Maintenance Service Agreement

Home Comfort Assurance Program

Avoiding major expenses in order to stretch your dollars is wise planning. With Groff”s Home Comfort Assurance Program you can prevent an HVAC failure and maximize the value of your dollar at the same time.

We have value priced our regular HVAC maintenance and service plan and added some money saving benefits for those who partner with us in the program. HVAC extended warranty programs require annual cleaning and servicing of your heating and cooling equipment. Regular maintenance not only safeguards extended warranty plans, but also helps minimize your risk of unwanted expenses by proactively preventing potential breakdowns of your heating and cooling system. With proper care, your unit will run better — longer.
